Outline of Final Research Achievements

The domestic production of plastics has been over 10 million tons. The improvement of the efficiency of the production process is important for energy saving. The comprehensive understanding of curing process of polymers is essential for the development efficient polymer production process. In this study, we investigated the thermophysical properties of polymer layer during curing process at the single-molecular scale using single molecule tracking (SMT) method. The SMT method enables us to investigate or diffusion coefficient or the viscosity of the polymer in which the probe molecule travels. As a result, we found that there were some diffusive states in the polymer layer investigated in this study.

Academic Significance and Societal Importance of the Research Achievements

高分子の硬化過程におけるSMT計測を実施した.巨視的には粘度が一様に上昇していくような系において,SMT計測のスケールでは粘性分布に空間的な不均一性が現れていることが分かった.またこのように現れる膜中の粘度の高低分布をみると,柔らかい領域,硬い領域がそれぞれクラスターを形成しており,これらの相関長の経時変化を解析することで不均一分布の性質を調査した.微細なスケールにおける分子個々の熱運動が,マクロスケールで計測される物理量とどのように関係付けられるかに関しては学術的にも非常に興味深い課題であると考えられると同時に,高分子材料製品の製造の高度化・高効率化につなげる基盤構築に有用な知見となる.
